Nowadays, we refer to “bubbles” as online places where no information from outside is allowed in. But in this instance, the opposite is true: the bubbles are a tool to help visualise how well one set of books is performing, compared to other sets of books. The OAPEN Library is an open online platform, and recently we have audited ourselves, based on the POSI principles. However, apart from an infrastructure, it is also a library.
When our collection passed the 20,000 titles milestone, we felt it was time to assess our collection: how well does it perform? That is not a simple question to answer: assessments of libraries and their collections are taking place within a certain context. OAPEN is not a ‘traditional’ library with a mixed collection of physical and digital publications, and our collection criteria are perhaps a bit different: books should be peer reviewed and have an open license, but we welcome all languages and subjects. We are not linked to one ‘parent organisation’, but try to serve everybody.
Three types of stakeholders support the OAPEN Library: publishers, funders and libraries. Both publishers and funders contribute to the collection by making publications available. They will be interested in the dissemination of the books and chapters. For libraries, the composition of the collection will be paramount. How do the titles on offer fit within the information needs of their patrons?
The evaluation of the OAPEN collection should consider these two aspects. The dissemination of books and chapters is measured through the number of downloads – based on COUNTER R5 conformant data. The composition of the collection is measured among two axes: subject and language. Both dissemination and the content-related aspects are paired to the number of publications. So, we have to take into account three dimensions: number of titles, number of downloads and average downloads per title. On top of that, we need to look at the differences between languages and subjects. All in all, a complex mix.
Our solution was to use three-dimensional pictures: the bubbles.
The bubbles display the composition of the collection and how its readers make use of it. Visualisations like this help to tell a complicated story in a simple way; a powerful instrument to guide the further development of the OAPEN Library.
